Psycopg2.operationalerror: scram authentication requires libpq version 10 or above

The error “psycopg2.operationalerror: scram authentication requires libpq version 10 or above” occurs when there is a mismatch between the version of libpq (PostgreSQL C library) installed on your system and the version required by psycopg2.

The Simple

You can update libpq to version 10 or above to resolve this error. To do so, follow the steps below:

1. Update libpq using your package manager, such as apt, yum, or brew:
   • For apt package manager:

                 
                   sudo apt-get install libpq-dev
                 
               

   • For yum package manager:

                 
                   sudo yum install postgresql-devel
                 
               

   • For brew package manager:

                 
                   brew install libpq
                 
               

2. Once libpq is updated, reinstall psycopg2 to ensure it uses the updated version:

           
             pip uninstall psycopg2
             pip install psycopg2
           
         

It is also essential to consider the following cases:

• If you are using a virtual environment, make sure to activate it before running the pip commands mentioned above.
• If you have multiple versions of libpq installed on your system, the wrong version might be picked up by psycopg2. In such cases, you may need to specify the correct version in your system’s PATH environment variable or use a package manager specifically for your virtual environment.
